Talkback Button
There may be times when the console operator wants to talk to one of the
talent in the Studio. When the TALKBACK button in the Studio Monitor
section is pressed the operator’s mic will interrupt the speaker feed that is
normally heard in the studio.
If the Producer talkback port has been activated, the audio from that port
will override both the studio source selection and the console TALKBACK
interrupt.
If there is a live mic in the studio which has activated the mute feature,
talkback will also be muted in the speakers. However, if the installer has
provided a headphone feed to the studio, that feed will not be muted.
Talkback to phone callers is accomplished via the phone CUE BUTTON,
as previously described.
Meter Section
The METER SECTION consists of two VU METER PAIRS, a METER
SELECT BUTTON, and a METER DISPLAY.
VU Meter Pairs
The VU METER PAIRS are stereo LED bargraph type meters. The level
of the signal being metered is indicated by the number of display elements
that are lighted. The more elements lighted, the stronger is the signal being
displayed. The top three LEDs in each bargraph are red (the rest are green)
to indicate when the signal level is approaching a clipping (distorted) level.
The left member of the pair indicates the level of the signal’s left channel,
while the right member of the pair indicates the level of the signal’s right
channel.
The first VU METER PAIR shows the level of the PGM output, while the
second VU METER PAIR (the SWITCHED METER PAIR) shows the level
of the signal that is selected for it.
The SWITCHED METER PAIR can meter any signal appearing at a
console input connector, in which case the input’s left signal appears on the
left meter and the input’s right signal appears on the right meter.
The SWITCHED METER PAIR can also meter PGM, AUD, or the
combination of MONO1 and MONO2, with MONO1 appearing on the left
meter and MONO2 on the right meter.
The SWITCHED METER PAIR can also meter the caller feed mix-minus
buses (CF1 on the left meter and CF2 on the right meter), or the general
purpose mix-minus buses (MXM1 on the left meter and MXM2 on the right
meter).
If any channel is placed in cue, or if the TALKBACK button is being held
down, the SWITCHED METER PAIR will automatically switch to meter
CUE on the left meter and the console’s talkback bus on the right meter. The
SWITCHED METER display (see below) switches to show “Q/TB”.
